Mystery line appears when importing Inkscape DXF to T2Laser

I'm just getting used to my new A3 Pro and am wanting to use it in my Pepakura projects. I've exported my prints as vector PDFs into Inkcape, which then is used to make them into DXF files. While this seems to be working, an odd line has appeared in T2Laser between two points that cross my work piece. Is there any way to remove this line?
